Journal ArticleDOI
Improved Left Ventricular Mechanics From Acute VDD Pacing in Patients With Dilated Cardiomyopathy and Ventricular Conduction Delay
David A. Kass,Chen Huan Chen,Cecilia W. Curry,Maurice Talbot,Ronald D. Berger,Barry J. Fetics,Erez Nevo +6 more
TL;DR: VDD pacing acutely enhances contractile function in heart failure patients with intraventricular conduction delay and single-site pacing at the site of greatest delay achieves similar or greater benefits to biventricular pacing in such patients, to clarify pacing-effect mechanisms.
Journal ArticleDOI
Left ventricular or biventricular pacing improves cardiac function at diminished energy cost in patients with dilated cardiomyopathy and left bundle-branch block
Gregory S. Nelson,Ronald D. Berger,Barry J. Fetics,Maurice Talbot,Julio C. Spinelli,Joshua M. Hare,David A. Kass +6 more
TL;DR: Ventricular resynchronization by left ventricular or biventricular pacing/stimulation in DCM patients with left bundle-branch block acutely enhances systolic function while modestly lowering energy cost should prove valuable for treating DCM Patients with basal dyssynchrony.
Journal ArticleDOI
Cardiac resynchronization and death from progressive heart failure: a meta-analysis of randomized controlled trials.
David J. Bradley,Elizabeth A. Bradley,Elizabeth A. Bradley,Kenneth L. Baughman,Kenneth L. Baughman,Ronald D. Berger,Hugh Calkins,Steven N. Goodman,David A. Kass,Neil R. Powe +9 more
TL;DR: In this paper, the authors conducted a meta-analysis of randomized controlled trials to determine whether cardiac resynchronization reduces mortality from progressive heart failure in patients with symptomatic left ventricular dysfunction.
Journal ArticleDOI
Beat-to-Beat QT Interval Variability: Novel Evidence for Repolarization Lability in Ischemic and Nonischemic Dilated Cardiomyopathy
Ronald D. Berger,Edward K. Kasper,Kenneth L. Baughman,Eduardo Marbán,Hugh Calkins,Gordon F. Tomaselli +5 more
TL;DR: DCM is associated with beat-to-beat fluctuations in QT interval that are larger than normal and uncoupled from variations in heart rate, which indicates that DCM leads to temporal lability in ventricular repolarization.
Journal ArticleDOI
Pulmonary Vein Anatomy in Patients Undergoing Catheter Ablation of Atrial Fibrillation Lessons Learned by Use of Magnetic Resonance Imaging
Ritsushi Kato,Lars Lickfett,Glenn Meininger,Timm Dickfeld,Richard C. Wu,George J. Juang,Piamsook Angkeow,Jennifer LaCorte,David A. Bluemke,Ronald D. Berger,Henry R. Halperin,Hugh Calkins +11 more
TL;DR: It is demonstrated that AF patient have larger PVs than control subjects and the value of MRI in facilitating AF ablation is demonstrated.
